Answer 1

10) To find: If conditions for superposition are met, it is possible to find the slope and displacement at a point on a beam subjected to several different loadings by algebraically adding the effects of its various component parts. True •False e Soln i True Explanation; Slope or deflection of a beam is the sum of the slope or deflection produced by individual loads Principle of superposition: The deflection or slope at a given point in a Structure produced by several loads simultaneously on the structure con be found by superposing deflections or slope at the same point produced by loads acting individurally 2) To find! The variables used to denote slope and deflection are respectively Soln! O, v fact: used to denote slope to denote deflection V used

13) To find; points on the moment diagram where M=o correspond to what on elastic curve Boundary conditions zero deflection zero slope inflection point soln : Boundary conditions: Explanation : Equation of elastic curve : E I dry d x² e.g. simply supported at x=a Bending moment i zero = M = EI dy =0 da? xoa Free at x-a Bending moment is zero M = Eldry dx² こ0 ara (4) To find? which equation is referred to as curvature Soln! ㅗ S Explanation! Equation of curvature i given by I EI Where s = radius of curvature of elastic curve -
